T0 (LH whom, t Ina/y concern:

Be it known that I, VILLIAM L. AUSTIN, a citizen of the United Stetes, resdfng n Phledelphla, Fenns lvania, have invented certain Improvements in Locomotives, olE which the following is a specification.

The object of Inf-,f invention is to construct a locomotive of the Sngle-eXpanSon t; 'pe with an increased piston area without extending the el 'linders bejond the normal width of the locomotive. This object I attain in the following manner, reference being had to the accompanying drawgngs, in whfch" Figure l is a side view, partly in diagram, illustrating in v invention. Fig. 2 is an end view, also partly in diagram. Fig. 3 is a sect'ion on the line 3 3, Fig. 4, showing the c; Ender-casting. Fig. 4 is a sectional view on the line 4 4, Fig. 3; and Fig. 5 is a sectional view on the line 5 5, Fig. 3.

A locomotive is restricted in wfdth b v almost every ra.Y lroad, due to the width of tunnels, embankments, bridge-foundations, and structures at one S de of the track, and it is the common practice of railroads to lurn'sh a chart giving the maXmum width and height, and ell rolling-stock must be constructed so as to come within these limits. As locomotives have become more poweilil the entire space allowed by the ra lread eompanfes has been utilized, and at the present tfme the el linders are just wlthfn the maxfinuni limit; but heavier and more powerful locomotives are now demanded, and Ain order to suppl. the demand wfthout increasng the width I have divided the s'ngle cylinder into two parts, placing one under the other, the combined surface area of the pistons being greater than in engines heretofore buflt w-th s 'ngle ci lnders on eoeh sf de, and thfs arrangement enables me to build a powerful locomotive wfthn the specffied width required bv.' the raflroad companes.

Ilele ng now to the drawings, A is the boiler of the ordinary t; pe. o ay are the wheels.

(Shown bv dotted lines in Figs. 1 and 2.)

B B are the saddles of the locomotive,sup ported by the frame and 'I'ittfng the smokebox of the boiler in the usuel manner. These saddles each contain the two ci lQndersD D. In the present instance the cylinder D is arranged directly below the cilinder D, as clearly illustrated in Figs. 3 and Ll.

l) is the steam-inlet passage to the valvechest C, whfch :'s mounted above the clnder-cas. ng, and b is tlie exhaust lead.l ng Vfrom the central port Il to the exhaust-nozzle. d IZ are the steam-ports leadng from the chest to the ends o'l the eylnder D, and the side-valve is arranged to uncover the several ports in the ordnarv manner. It w.ll be understood that an form of valve may be used wthout depa.' .ng from m3,' invention; but in the present instance I have s mply shown the valve-suia'hzee arranged lor the side-valve of the D t: pe. Passages e e at each end of the cy llnder structure form cemmunlcatf ons between the c ,lrnders D and D', so that part of the steam admitted into one end of the cylinder D w..ll Ilowinto the same end of the c; .nder D', so that the p 'stons ol tlze c; ljnderswll travelln unson. The pistons F F are connected by rods fj" to a common cross-head F2, arranged to sl. de on waY 's "L i oi air, su.table construction, and the driving-wheels are connected to the cross-head in the ord.' na: manner.

B3' ths eonstructon it w ll be seen that I can bu. ld very powerful s ngle-expanslon locomotxe wlthout ine-reas. ng the width of the locomotive beyond the normal.

I clam- 1. The combfnaton in a locomotive ol the s 'ngle-expansion type, having two el lfnders on each s. de, one directly below the other, of a valve-chest suppl ed wlth steam drectly Vfrom the boler, tliere befng ports between one clfnder and the valve-chest, and passages at each end form.' ng direct connection between the cyLnders, sul:stantlall),A as descnb ed.

2. The combination in a locomotive of the Sngle-expansfon t; "pe, of two saddles, each saddle conta n ng two oylnders, one s. tuated below the other, there be.` ng passages at each end el the saddles'fermlng direct cominunfcatgcn between the two cjLnders, and a valvechest on each saddle suppl. ed 'with steam directljyT 'from the boler and having ports in the saddles lormng communfcatf on between one of the el l. nders and the valve-chest, substantialll.A es described.

In testfinon,Y whereof I have s'gned mv name to thfs speclicatfon in the presence of two subscribing witnesses.

IVM. L. AUSTIN.
